Used as a catalyst in organic synthesis, particularly in cyclopropanation and C–H bond functionalization reactions. It efficiently promotes the decomposition of diazo compounds to generate metal carbenoids, enabling the formation of carbon–carbon bonds under mild conditions. Commonly applied in the synthesis of complex molecules, including pharmaceuticals and natural products, due to its high selectivity and reactivity. Also employed in asymmetric catalysis when paired with chiral ligands, enhancing enantioselectivity in product formation.
